Explanation:

Step 1: Data given

For the reaction aA + bB ⇆ cC + dD

Kc = [C]^c * [D]^d / [A]^a [B]^b

a. SbCl5 (g) ⇄ SbCl3 (g) + Cl2 (g)

Kc = [Cl2]*[SbCl3] / [SbCl5]

b. 2 BrNO (g) ⇄ 2NO (g) + Br2 (g)

Kc = [Br2]*[NO]² / [BrNO]²

c. CH4 (g) + 2 H2S (g) ⇄ CS2 (g) + 4 H2 (g)

Kc = [H2]^41 * [CS2] / [H2S]²*[CH4]

d. 2CO (g) + O2 (g) ⇄ 2CO2 (g)

Kc = [CO2]² / [O2][CO]²
